초록

For most commercial radiation measurement equipment, manufacturers specify an operating temperature in the range of 0 to +40℃. However, in environments that exceed the quality assurance performance of the safeguards equipment, such as the winter environment in North Korea, the performance of the equipment deteriorates or normal use is impossible. In this study, safeguards equipment measurements were performed by creating an extreme temperature environment using a constant temperature and humidity test chamber. The safeguards equipment used in the evaluation was MIRION's Inspector-2000-based equipment, which evaluated the usability in extreme temperature environments using three types of detection units: NaI(Tl), CZT, and HPGe.
